The tester will return to normal operation automatically after it cools
down.
Cold Temperature Effects
Because of the chemical nature of the battery, it will test lower when
cold than when warm. For most accurate results, this effect should be
compensated for when the battery's internal temperature is below 40°F
(4.4°c). Assume the battery's internal temperature to be the day's
high-low average temperature. See Figure 2.
Example: If rated capacity is 800 ccA and internal temperature is approxi-
mately 35°F (1.7°c), assume test capacity to be 560 ccA. (800 ccA x 70%
(at 35°F) = 560 ccA)
